High-performance protective switchgear designed for immediate deployment in Jakarta commercial and industrial projects.
Navigating the complex electrical safety requirements of Indonesia’s economic center with specialized OFPM Series RCCB solutions.
The Special Capital Region of Jakarta (DKI Jakarta), particularly key business districts such as SCBD, Megakuningan, Sudirman, and Thamrin, hosts Southeast Asia's dense skyscraper developments and commercial complexes. Modern commercial infrastructure requires reliable low-voltage residual current protection to mitigate continuous electrical leakage risks caused by central HVAC networks, extensive LED lighting arrays, and heavy server loads. The OFPM Series Residual Current Operated Circuit Breakers provide high-sensitivity earth leakage detection (30mA for personnel safety, 100mA/300mA for equipment insulation monitoring), ensuring compliance with international IEC standards and preventing localized outages in commercial towers.
Surrounding Jakarta is Java’s largest industrial ecosystem—spanning Cikarang, Karawang, Pulo Gadung, Tangerang, and Bekasi. Factory campuses in these zones handle automotive manufacturing, electronics assembly, chemical processing, and food production. Industrial processing equipment generates dynamic inductive surges, harmonic distortion, and intermittent transient voltages. Standard circuit breakers often experience nuisance tripping or thermal breakdown under tropical factory conditions. The OFPM 2P and 4P series integrate flame-retardant enclosures, high-grade electromagnetic tripping coils, and enhanced arc-extinguishing chambers to maintain continuous operational uptime under demanding industrial conditions.
Engineering Insight: Operating electrical protective switchgear in Jakarta requires accounting for relative humidity levels consistently exceeding 85% and ambient temperatures reaching 38°C inside outdoor enclosure boxes. The OFPM Series incorporates specialized silver-nickel alloy contact terminals and anti-corrosive internal bimetallic components to eliminate contact oxidation and thermal drift.
Precision-built residual current protection designed to meet rigorous global IEC/EN 61008-1 and Indonesian local power requirements.
Unlike voltage-dependent electronic RCCBs that fail during neutral line breaks, the OFPM Series relies on a voltage-independent zero-sequence current transformer (ZSCT). This ensures 100% reliable tripping even under complete neutral wire failure or sudden supply voltage drops across Jakarta’s regional distribution grids.
Available in 2-pole (2P) single-phase and 4-pole (4P) three-phase configurations, supporting rated current ratings from 16A up to 100A. The OFPM Series provides rated residual operating currents ($I_{\Delta n}$) of 30mA for life safety, 100mA, and 300mA for electrical fire prevention in accordance with standard electrical codes.
Manufactured using high-impact, self-extinguishing polyamide resin (UL94-V0 rated), engineered to withstand extreme thermal stress, tropical ambient heat, moisture condensation, and corrosive industrial chemical vapours commonly found in maritime tropical environments.

Engineered to deliver seamless electrical protection across key industrial sectors and urban infrastructure.
In mega-structures such as Central Park Mall, Grand Indonesia, and SCBD office towers, hundreds of single-phase and three-phase branch circuits power elevators, chillers, and lighting arrays. The OFPM 4P RCCB prevents insulation breakdowns from causing cascading power failures, ensuring continuous public safety and equipment protection.
Industrial assembly lines utilize robotics, welding units, and heavy electric drives. Ground fault leakages in motor windings can cause costly line shutdowns. OFPM residual current breakers instantly detect micro-leakage currents, isolating fault zones before major short-circuits occur.
Jakarta’s rapidly growing digital economy relies on tier-3 and tier-4 data centers in Cyber 1 and BSD City. The OFPM series supports high-frequency filtration, preventing false trips from non-sinusoidal switching power supplies while providing uncompromised shock protection for maintenance crews.
With Indonesia accelerating its rooftop solar adoption across residential and commercial estates, the OFPM Type A/B RCCBs protect inverter AC outputs against pulsating DC earth fault currents, guaranteeing safety and grid compliance under PLN (Perusahaan Listrik Negara) connection rules.
Ensuring smooth procurement, regulatory certification, and technical alignment for contractors and OEMs in Jakarta.
All OFPM Series RCCBs are manufactured strictly to IEC 61008-1 standards and designed to satisfy standard SNI (Standar Nasional Indonesia) requirements for low-voltage electrical switchgear, simplifying local authority approvals and project commissioning.

Jakarta features high average relative humidity (80%–95%) and ambient outdoor temperatures reaching 38°C. The OFPM Series utilizes anti-corrosive bimetallic elements, silver-alloy contacts, and robust housing materials designed to prevent degradation, contact oxidation, and thermal tripping drift under high-humidity tropical conditions.
A Miniature Circuit Breaker (MCB) protects electrical circuits against overloads and short circuits. A Residual Current Operated Circuit Breaker (RCCB), such as the OFPM Series, monitors earth leakage current (current leaking to ground) to protect human life against fatal electric shocks and prevent electrical fires caused by insulation deterioration. For total protection, an RCCB is typically paired with an MCB or integrated as an RCBO.
Yes. The OFPM Series operates at standard nominal single-phase (230V AC) and three-phase (400V AC) voltages at 50Hz, fully matching Perusahaan Listrik Negara (PLN) grid configurations across Jakarta and Indonesia.
