Product FAQs
7 answersWhich Siemens panelboards are compatible with the HED42B100 circuit breaker?
This bolt-on breaker is designed for use in Siemens Sentron panelboards, including P1, P2, and P3 models, as well as SB series switchboards. You must verify that your specific panel interior is configured to accept ED frame breakers.
How does the HED4 series differ from standard ED4 breakers?
The HED4 series is the high-interrupting version of the standard ED4 frame. While sharing the same physical footprint, the HED42B100 provides a 42kA interrupting capacity at 480VAC for systems requiring higher fault current protection.
What wire sizes are accepted by the terminals on the HED42B100?
The factory-installed lugs accept wire gauges from 10 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors. Always ensure proper torque specifications are applied during installation.
Can the HED42B100 be used in DC voltage systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, where it provides a 30kA interrupting capacity.
Are the trip settings on the HED42B100 adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous protection functions without user-adjustable dials.
Does this breaker require a specific mounting hardware kit?
As a bolt-on ED frame breaker, it requires the correct strap kit or mounting hardware specific to the panelboard or switchboard it is being installed in, such as a P1 or P2 panelboard mounting kit.
What type of fault protection does the HED42B100 provide?
This thermal-magnetic breaker provides standard long-time and instantaneous (LI) trip functions. The thermal element protects against sustained overloads, while the magnetic element trips immediately during short-circuit faults.
