Description
Built for industrial applications, this 30A, three-pole breaker provides 30mA ground fault equipment protection (GFEP). It protects sensitive commercial machinery from line-to-ground faults. This bolt-on component mounts into Siemens P1 through P5 panelboards. The lug terminals accept 10-6 AWG copper or aluminum wire for reliable integration. With a high interrupting capacity of 65 kAIC at 208Y/120VAC, the B330EGHH utilizes fixed thermal-magnetic trip technology and is HACR rated for HVAC use.Specifications

Product FAQs
7 answersIs the B330EGHH suitable for personnel ground fault protection?
No. The B330EGHH is a Ground Fault Equipment Protection (GFEP) breaker with a 30mA trip threshold. It is designed to protect machinery from line-to-ground faults. For 5mA personnel protection, a GFCI breaker like the B330GFHH is required.
How is the neutral connected on the B330EGHH breaker?
This breaker features a pigtail neutral wire. The pigtail must be routed and terminated at the panelboard neutral bus to power the internal ground fault monitoring circuitry.
What does the EGHH suffix indicate on this Siemens breaker?
The EG indicates it is an Equipment Ground Fault Protection breaker with a 30mA trip level. The HH designates a high interrupting rating, providing up to 65kAIC at 240V.
Which Siemens panelboards accept the B330EGHH breaker?
This bolt-on breaker is compatible with Siemens P1, P2, P3, P4, and P5 panelboards. It secures directly to the busbar, making it suitable for commercial and industrial distribution.
What wire sizes are supported by the B330EGHH terminals?
The integrated lugs accept 10 AWG to 6 AWG copper or aluminum conductors. Always apply an approved oxide inhibitor when terminating aluminum wire.
Are the trip settings adjustable on the B330EGHH?
No. This breaker utilizes fixed thermal and fixed magnetic trip elements for overcurrent and short-circuit protection, along with a fixed 30mA ground fault threshold.
Is the B330EGHH rated for use with HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration applications that require 30mA equipment ground fault protection.
