Tronic MG 250L-0250-04 is a 4 pole moulded case circuit breaker (MCCB) that protects a three phase and neutral supply from overload and short circuit. It is rated for 400/415V AC, 50/60Hz, with an 18kA breaking capacity. The red toggle shows ON clearly, and a push to trip button lets you test that the breaker trips. It suits main and sub-main protection in commercial buildings, workshops, factories, pump houses and distribution boards, where a standard miniature breaker is too small for the load.
