Westinghouse | RKL2300L | Circuit Breaker | 300A | 2-Pole | 600V | Bolt-On

The Westinghouse RKL2300L Circuit Breaker delivers robust overcurrent protection in a compact bolt-on package, engineered for demanding service environments. With a 300-amp rating, 2-pole configuration, and 600-volt capacity, this unit is designed for maintenance, retrofit, and replacement projects where exact specifications matter.

Key specifications

• Amperage: 300 A
• Poles: 2-Pole
• Voltage: 600 V
• Mounting: Bolt-On

Why this Westinghouse breaker stands out

Unlike plug-in options, the bolt-on design provides a secure, vibration-resistant connection ideal for panels in commercial and light industrial settings. The RKL2300L is a precise match for projects where only the exact specifications will ensure reliable operation and compatibility with older equipment.

Ideal uses and scenarios

• Maintenance and repair work in service panels that require the exact Westinghouse RKL2300L specs.
• Retrofits where upgrading to a higher-current or more robust protection device is needed without changing the panel architecture.
• Replacement of failed units in systems previously equipped with the RKL2300L or equivalent 2-pole, 600V bolt-on breakers.

Installation and compatibility tips

Before ordering, verify fit and ratings to avoid mismatches. The part number RKL2300L is the most reliable reference for compatibility with your panel and bus configuration. This breaker is intended for use in panels and switchgear that support bolt-on mounting and the specified amperage, voltage, and pole configuration. For electricians, ensure the enclosure allows bolt-on mounting and that the bus stabs align with the device's terminals.

What problems does it solve?

By providing precise 300A overcurrent protection in a bolt-on format, it helps prevent electrical faults, reduces nuisance tripping, and supports safer, faster maintenance cycles. It’s ideal for aging installations where the original equipment is still functional but requires a modern, compatible breaker to restore reliable protection.

Maintenance and care

Keep terminals clean and free of corrosion. Periodically inspect the mounting hardware and ensure tight connections to maintain optimal protection performance. Only qualified personnel should perform installation or replacement to comply with safety standards.
