Description

Serving as a substitute for the legacy BE230, this 30-amp component provides dedicated 30mA equipment ground fault protection. It is calibrated to shield industrial machinery from damaging leakage currents. The device mounts into Siemens P1 through P5 panelboards. A rugged bolt-on configuration maintains secure contact in high-vibration environments. With a 10kA interrupting capacity at 120/240VAC, this Type BL unit incorporates thermal-magnetic trip technology and is HACR rated.

Product FAQs

8 answers
Which Siemens panelboards are compatible with the B230EG breaker?

This bolt-on breaker mounts directly into Siemens P1, P2, P3, P4, and P5 panelboards.

What type of ground fault protection does the B230EG provide?

It provides Ground Fault Equipment Protection (GFEP) with a 30mA trip threshold. This level is specifically calibrated to protect machinery and heat trace cables from equipment-damaging leakage currents, rather than the 5mA threshold used for personnel protection.

How is the neutral configured for the ground fault circuit on this breaker?

The breaker includes a factory-installed pigtail neutral wire. This pigtail must be terminated at the panelboard neutral bus bar to power the internal ground fault sensing circuitry.

Can the B230EG replace legacy equipment protection breakers?

Yes, it serves as a direct modern substitute for the legacy Siemens BE230 bolt-on equipment protection breaker.

What are the acceptable wire sizes for the load terminals on the B230EG?

The lug terminals will accept 10 AWG to 8 AWG copper conductors, or 10 AWG to 6 AWG aluminum conductors. Ensure proper torque specifications are met during installation.

What is the advantage of the bolt-on connection for this GFEP breaker?

The bolt-on mounting secures the breaker directly to the panelboard bus, preventing it from vibrating loose in demanding commercial or industrial environments where heavy machinery operates.

What do the LIG trip functions indicate on the B230EG?

The LIG designation means the breaker incorporates Long-Time for overload protection, Instantaneous for short-circuit protection, and Ground Fault sensing for equipment protection. This provides comprehensive thermal-magnetic and leakage coverage.

Are the thermal-magnetic or ground fault trip settings adjustable on this unit?

No, all protective trip thresholds on the B230EG are fixed at the factory and cannot be field-adjusted by the installer.
