[Mitsubishi Electric] - B-N100 Main Circuit NC Magnetic Contactor (AC Operated, 120A Ith, 2a2b Aux)

Mitsubishi Electric MS-T/N series B-N100 magnetic contactor with normally closed b-contact main circuit, for DC motor starting resistor short-circuiting, AC motor slow-start duty, dynamic braking and AC or DC source changeover in lighting circuits. AC operated coil, main contact configuration 1a2b, 2a2b twin auxiliary contacts rated down to 20V 5mA. Open thermal current 120A, coil power consumption 2.9W. Phase barriers fitted as standard on the main circuit; charged-part protection cover units UN-CV and UN-CZ are applicable. Mechanical durability 5,000,000 operations, electrical durability 500,000 operations at 1200 operations per hour. Compliant with JIS C8201-4-1, JEM1038 and JIS C8201-5-1. AC operated DC excited electromagnet eliminates coil humming and provides a wide-input common rating coil with built-in surge absorption.
