The Siemens JD62F400 is a circuit breaker frame. It has 2 poles, rated current of 400A, rated voltage of 600VAC and an interrupting rating of 35kAIC@480V. This Sentron series breaker has a JD frame and bolt-on mounting. It features a load side lug terminal connection and standard protection. This listing is the frame only. A compatible trip unit is required and is not included.
What does the two-pole, single-phase configuration mean for circuit selection?
The two-pole construction switches and protects two circuit conductors in a single-phase application. Select it when the circuit requires two-pole interruption.
How is this breaker mounted?
It uses bolt-on mounting, so installation involves securing the breaker mechanically with bolts rather than using a plug-in attachment. Plan the mounting work around that fastening method.
How are the outgoing conductors connected?
The load-side connection uses a lug, which mechanically clamps the outgoing conductor. Plan the load-side termination work around a lug connection.
How should I use the Siemens JD62F400 interrupting rating when selecting it?
The interrupting rating is 35kAIC@480V. For selection at that voltage, ensure the available fault current at the installation point does not exceed this interrupting rating.
