Miniature Circuit Breakers - 5SJ4 Branch Protectors

5SJ4 miniature circuit breakers (MCB’s) are 1-, 2-, and 3-pole thermal magnetic overcurrent protection devices that are intended for general industrial use such as branch circuit protection in both IEC and NEMA applications.  In addition to their UL 489 standard compliance, these miniature circuit breakers are CE marked according to EN/IEC 60 898 which makes them suitable for international applications.  5SJ4 MCB’s are available from 0.3A to 63A with short circuit current ratings up to 14kA @ 240VAC and 10kA @ 60VDC.

The 5SJ41 (1 Pole) are available in either "Same Polarity" which are not suitable for Reverse Feed Connections or "Opposite Polarity" which are suitable for Reverse Feed Connections.  The 2  and 3 Pole versions are both suitable for Reverse Feed Connections.

Features

  • 0.3 to 63 Amps
  • 1, 2 & 3 pole versions
  • Voltage up to 240 VAC (50/60Hz) with 14kA IC
  • Voltage up to 60 VDC with 10kA IC
  • Trip Curves B, C and D
  • 35 mm DIN rail mounting
  • Touch Safe Terminals
  • Visible Indicator for ON and OFF/Trip
  • Approved for field wiring applications. 
  • Approved to UL489, CSA 22.2 No.5-02 and EN/IEC 60898
