UL 489 Listed MCCB, UL Compliant Product

Caution
- This product belongs in RoHS Directive under Category 9 "Monitoring and control equipment" with exclusion from the usage restriction of phthalate esters until 21 July 2021.
Product Description
- Low-Voltage Circuit Breakers MCCB (Molded Case Circuit Breakers) NF series from Mitsubishi electric. - The molded case circuit breaker (MCCB) opens and closes a low voltage circuit and breaks the fault current (an overload current or short circuit current) automatically, to protect the wirings/conductors of the circuit. - MCCB (Molded Case Circuit Breakers) NF series have 4 types available, NF-C (Economy type), NF-S (Standard type), NF-H (High-performance type) and NF-U (Current limiting-type ultra-breaker). - Rated ambient temperature 40°C. - Number of poles is up to 4. - Rated current can be select up to 440 A.
