Short Description

The TOMZN TOB1-63H C40 is a 40A, two-pole AC miniature circuit breaker with a C tripping curve. The attached unit is marked for 400V AC operation and 6kA breaking capacity, providing overload and short-circuit protection for suitable low-voltage distribution circuits.

Long Description

Protect AC distribution circuits with the compact TOMZN TOB1-63H C40 miniature circuit breaker. This two-pole C-curve model is rated at 40A and uses a mechanically linked handle so both poles operate together.

TOMZN positions the TOB1-63 series for lighting and motor distribution systems requiring overload and short-circuit protection. The manufacturer states that multipole variants are intended for AC 50/60Hz circuits up to 415V and that the enclosure components use high fire-resistant, shock-resistant plastic. The supplied product label identifies this exact C40 unit as 400V AC with a 6000A breaking capacity.

The breaker can also be used for infrequent switching of electrical equipment and lighting circuits within its rated conditions. Selection, coordination and installation must be completed by a qualified electrician according to the applicable wiring rules and the requirements of the connected circuit.
