The Merlin Gerin C60HB is a 3-pole miniature circuit breaker from the Multi9 range, B16 series, rated at 16 A with a breaking capacity of 10 kA at 415 V AC.
This unit is offered in used condition, which is common for a breaker of this vintage. A used C60HB is functionally identical to a new one as long as it has not been subjected to a fault event — the thermal-magnetic mechanism is fully mechanical and does not degrade in storage.
Standard DIN-rail mount, 3-pole. Dimensions 81 x 72 x 70 mm fit standard enclosure cutouts.
