Capable of handling demanding electrical loads, this 90-amp molded case circuit breaker features a rugged bolt-on design for commercial distribution systems. It integrates seamlessly into Siemens P1, P2, and P3 panelboards, providing fixed thermal-magnetic trip functions. The device achieves an impressive 100kAIC at 240VAC and 65kAIC at 480VAC, making it suitable for high-fault environments. While this specific ED-frame model is active, Siemens is transitioning future designs to the 3VA series.
What panelboards are compatible with the HHED62B090?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as compatible switchboards.
What wire size and material can be used with the lugs on this breaker?
The included lugs accept 10 AWG to 1/0 AWG wire and are rated for both copper and aluminum conductors.
Can this breaker be used in DC applications?
Yes, the HHED62B090 is rated for DC applications up to 250VDC with an interrupting capacity of 10kAIC.
What is the difference between the ED4, ED6, HED4, and HHED6 breakers?
These are all Siemens Sentron ED frame breakers but they have different interrupting ratings. The HHED6 series offers the highest interrupting capacity in this frame size, rated at 65kAIC at 480VAC.
Does this breaker mount to a DIN rail or bolt directly to the bus?
The HHED62B090 is a bolt-on circuit breaker that mounts directly to the panelboard bus. It is not designed for DIN rail mounting.
What trip functions are included in this breaker?
This thermal magnetic breaker features fixed long time and instantaneous (LI) trip functions for overload and short circuit protection.
Can the HHED62B090 be reverse fed?
Yes, Siemens ED frame circuit breakers, including the HHED62B090, can be reverse connected.
