The Phoenix Contact 0700020 is a compact thermal circuit breaker from the CLIPLINE series, specifically the TCP.../DC32V sub-series. It is designed to protect 12V and 24V on-board systems and devices in vehicles and boats, as well as low-voltage systems in solar chargers.
This circuit breaker has a nominal current rating of 20A and a nominal voltage rating of 32V DC. It features a push-to-reset actuator, allowing for easy restoration of power after a fault. The voltage drop at nominal current is less than 150mV. It operates within an ambient temperature range of -30°C to +60°C.
The TCP.../DC32V thermal circuit breaker fits in fuse holders designed for flat-type fuse inserts according to ISO 8820-3 (DIN 72581-3). It can be plugged onto UK 6-FSI/C... fuse base terminal blocks with screw connection technology or ST 4-FSI/C... with spring-cage connection technology. Potential distribution can be conveniently implemented for both terminal types using bridges.
Key specifications include a 1-pole design, a limit short circuit interruption capacity of at least 3 interruptions of 150A or 1 interruption of 2000A, and a service life of 300 cycles at up to 50A. The degree of protection is IP30 for the operating field and IP00 for the connection area.
