TREF1 63A 3p, Thermal Adjustable Following IEC60947-2 ELCB
Inquire NowDescription
The TRE series ELCB (Earth Leakage Circuit Breaker) stands out for its adherence to international safety standards, specifically IEC/EN 60947-1 and IEC/EN 60947-2, making it a reliable choice for low-voltage switchgear and controlgear applications. Designed for both professional and industrial environments, it ensures the highest levels of protection against overloads, short circuits, and ground faults.
This versatile circuit breaker is available in both fixed and adjustable types, catering to various operational needs. With a range of features including multiple pole configurations (2-poles and 3-poles), breaking capacities (S-type and H-type), and rated currents (from 15A up to 63A), the TRE series ELCB is engineered to deliver optimal performance.
Additionally, the unit’s operational parameters are well-suited for standard installation conditions, including an ambient temperature range of -5°C to +40°C and an altitude of up to 2000m. Its robust design is aimed to function efficiently in environments with minimal pollution and electromagnetic interference.
