Introduction:ZSM2-1 Miniature Circuit Breakers is our energy-restricting circuit-breaker that has high performance values and that is equally suitable for the industrial sector, for commercial use and for installation at home. If a short-circuit occurs, it guarantees excellent selectivity conditions to upstream overcurrent circuit breakers while the load on equipment that is connected downstream is limited to a minimum amount.
ZSM2-1 MCBs in accordance with standard EN 60898-1.This standard is for electrical installation material for household installations and for similar purposes.
ZSM2-1 Circuit Breakers offer the fastest, and most flexible installation experience and completely eliminates safety concerns during maintenance and operation.they are engineered to adapt to the most challenging networks and environments while remaining cost effective over time. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire
ZSM2-1 Circuit breaker has a unique bottom-fixing auxiliary contact for saving space and time. It is designed for fast installation, reliability, and superior circuit protection.
ZSM2-1 MCB offers the right high performance MCB with high-rated breaking capacities and various tripping characteristics.High nominal current range of up to 80A.
ZSM2-1 MCBs can be made with B, C, D type. Type B tripping characteristic: the tripping current is (3 ~ 5) In, which is suitable for household distribution system, household appliances protection and personal safety protection. Type C tripping characteristic: the tripping current is (5-10) In, which is suitable for protecting distribution lines, lighting lines and motor circuits with high connecting current. Type D tripping characteristic: the tripping current is (10 ~ 20) In, which is suitable for protecting equipment with high impulse current, such as transformer, solenoid valve, etc.
ZSM2-1 MCB is used for overload and short-circuit protection of lighting, distribution lines, equipment in office buildings, residential buildings and etc. It can also be used for infrequent on-off operations and conversion of lines.
