Why Choose the ABB S402M-UCZ0.5 DC Miniature Circuit Breaker?
The ABB S402M-UCZ0.5 is a high-performance two-pole miniature circuit breaker (MCB) designed for reliable protection of DC circuits within the ABB SMISSLINE TP plug-in distribution system. With a low 0.5 A rated current and sensitive Type Z tripping characteristic, it provides dependable overload and short-circuit protection for electronic, control, instrumentation and auxiliary circuits.
As part of the ABB S400M-UC series, the S402M-UCZ0.5 combines thermal-magnetic circuit protection with the flexibility of the SMISSLINE TP architecture. Its two-pole configuration enables simultaneous switching and protection of two conductors, while the plug-in design supports efficient installation, maintenance and modification of compatible electrical distribution assemblies.
The S402M-UCZ0.5 supports two-pole operation up to 440 V DC and has a rated ultimate short-circuit breaking capacity of 25 kA at 440 V DC. Its sensitive Type Z characteristic makes it particularly suitable for protecting low-current electronic and control equipment where rapid magnetic operation at relatively low fault-current multiples is required.
