B230GF - Siemens 30 Amp 2 Pole 120/240V Bolt-On Molded Case Circuit Breaker, 10kA Interrupt Rating, GFCI, Thermal-Magnetic Trip, Class A Protection, Frame B

Product Overview

The Siemens B230GF is a 30 amp, 2-pole bolt-on molded case circuit breaker designed for 120/240V systems. It combines thermal-magnetic trip protection with an integrated ground-fault circuit interrupter (GFCI) and is rated for 10 kA interrupting capacity in a B-frame enclosure.

This SKU (B230GF) is a single-variant product. Confirm the B230GF model number when specifying for replacement or new installations.

Key Features

• 30 amp, 2-pole configuration for 120/240V branch circuits
• Integrated GFCI (ground-fault protection)
• Thermal-magnetic trip mechanism
• 10 kA interrupting rating
• Bolt-on molded case, Frame B

Function and primary protection

The B230GF provides combined overcurrent and ground-fault protection in a single device. It uses a thermal-magnetic trip for overload and short-circuit protection and includes a built-in ground-fault circuit interrupter (GFCI) for detection of earth leakage conditions.

• Overload and short-circuit protection via thermal-magnetic trip
• Ground-fault protection integrated into the breaker (GFCI)

Electrical ratings and configuration

This SKU is specified as a 30 amp, 2-pole breaker intended for 120/240V systems and carries a 10 kA interrupting rating. It is identified as a Frame B device suitable for applications that require these electrical characteristics.

• Ampacity: 30 A
• Poles: 2 (handles a 120/240V branch circuit)
• Interrupting rating: 10 kA

Mounting and physical configuration

The B230GF is a bolt-on molded case breaker in a Frame B configuration. Bolt-on mounting means it is designed to be fastened into a compatible panel or load center that accepts bolt-on style breakers.

• Mounting: bolt-on molded case
• Frame: B

Safety and trip characteristics

The breaker combines thermal-magnetic trip characteristics with Class A ground-fault protection. These features address overloads, short circuits and ground-fault/leakage conditions commonly considered for personnel protection and equipment safety.

• Trip type: thermal-magnetic
• Ground-fault protection: GFCI (Class A)

Before You Order

Confirm the model number (B230GF) and the panel’s compatibility with bolt-on Frame B breakers before ordering. Verify that the breaker’s electrical ratings (30 A, 2-pole, 120/240 V, 10 kA interrupting rating) and GFCI functionality meet your application and local code requirements.

• Confirm panel accepts bolt-on Frame B breakers.
• Verify required ampacity, pole count and voltage for the circuit.
• Ensure GFCI and Class A ground-fault protection are appropriate for the application.
