NEF211030 - 30Amp Circuit Breaker

NEF211030 - 30Amp Circuit Breaker

The NEF211030 30 Amp circuit breaker is built to protect individual branch circuits from overloads and short circuits in 120/277VAC electrical systems. As a 1-pole, thermal magnetic breaker in the NEF frame series, it’s designed for consistent, everyday performance in commercial and light industrial panelboards. The bolt-on mounting style creates a tight, secure connection to the bus, which helps maintain proper electrical contact over time. If you’re replacing a worn or tripped breaker or performing panel maintenance, this model delivers the protection and fit you expect from a properly matched NEF-frame device.

Key Features and Benefits

• 30 Amp, Single-Pole Design: Protects one circuit rated up to 30 amps from overload and short circuit conditions.
• Thermal Magnetic Trip Unit: Uses a dual-trip system—thermal for sustained overloads and magnetic for instantaneous faults—to respond accurately to different types of electrical issues.
• Bolt-On Connection: Secures directly to the panelboard bus for a firm, stable installation that helps reduce movement and connection problems.
• Molded Case Housing: Made with durable insulating materials designed for long service life in standard electrical environments.
• Strong Interrupting Ratings: Rated at 14kA at 277VAC and 18kA at 120VAC for reliable fault interruption within its specified limits.
