M3 160F - thermal-magnetic circuit breaker with earth leakage protection integrated 4P - Icu= 36kA - In= 160A
Description

Megatiker M3 160, moulded case circuit breaker for switching, control isolation and protection of low voltage lines. Protects a circuit from damage caused by excess current from an overload or short circuit

Product characteristics
  • Breaking capacity of 36kA, according to EN/IEC standard 60947-2, suitable for protection of high power industrial installations
  • Rated insulation voltage of 500V - Rated impulse withstand voltage of 6kV
  • Protection unit with rotary knobs for manual adjustment:- thermal protection with manual adjustment range of 0.8 to 1.0 of the rated current- magnetic protection fixed at 10 time the rated current
  • Supplied with fixing screws, screws for connections and insulated shields (phase barriers)
  • Can be equipped with auxiliaries (shunt release, undervoltage release, auxiliary contact), rotary handle, spreader, rear terminals, locking accessory, cage terminals (Al max. 80A) and high capacity cage terminals (for Cu/Al cables, with Cu and Al, 1x95mm² max. for flexible cables and 1x 120mm² max. for rigid cables)
