CHN240GF 40 Amp Double Pole GFCI Breaker Cutler Hammer

Description

Product Overview

The CHN240GF is engineered as a 40 Amp double‑pole GFCI circuit breaker, specifically designed for 240 V applications where safety and reliability are paramount. Constructed with high‑grade copper contacts and a robust polymer housing, this breaker meets the rigorous standards of UL listing and offers a 10 kAIC (kilo‑ampere interrupt capacity) rating, ensuring it can safely interrupt fault currents without damage to the surrounding electrical system.

Cutler Hammer, a trusted name in electrical components, integrates a pigtail neutral connection directly into the breaker, simplifying installation and reducing the chance of wiring errors. The breaker’s internal GFCI sensor detects ground‑fault currents as low as 5 mA, providing immediate tripping to protect both people and equipment. Its compact dimensions—6.42 × 3.66 × 2.2 inches—allow it to fit comfortably into standard load centers, while the 14.89‑ounce weight contributes to a solid, durable feel.

Beyond its technical specifications, the CHN240GF offers practical benefits: easy visual identification with clear labeling, a sturdy toggle for manual testing, and a design that minimizes nuisance trips while maintaining high sensitivity. Whether installed in a new construction project or retrofitted into an existing panel, this breaker delivers consistent performance, helping users meet NEC (National Electrical Code) requirements without compromise.

Usage

This breaker is ideal for protecting high‑power appliances such as electric ranges, water heaters, HVAC units, and workshop equipment that operate on 240 V circuits. Its double‑pole configuration ensures both hot legs are monitored simultaneously, providing balanced protection across the entire load. Electricians and DIY enthusiasts alike will appreciate the straightforward installation process: connect the pigtail neutral to the panel’s neutral bus, align the breaker with the appropriate phase, and secure it in the panel’s slot.

In commercial settings, the CHN240GF serves as a reliable safeguard for machinery and office equipment that demand continuous operation. Its rapid response to ground faults helps prevent costly downtime and protects sensitive electronics from damage. The breaker’s UL‑listed status also satisfies insurance and inspection requirements, making it a trusted choice for contractors who need to deliver code‑compliant solutions on schedule.

FAQ

What does a double‑pole GFCI breaker protect?

A double‑pole GFCI breaker monitors both hot conductors in a 240 V circuit. It detects imbalances caused by ground‑fault currents and trips the circuit, protecting people from electric shock and preventing damage to connected equipment.

Can I install this breaker in an existing panel?

Yes. The CHN240GF is designed to fit standard panel slots. The pigtail neutral connects to the panel’s neutral bus, and the breaker aligns with the appropriate phase. Always follow local codes and, if unsure, consult a licensed electrician.

What is the significance of the 10 kAIC rating?

The 10 kAIC rating indicates the breaker’s ability to safely interrupt fault currents up to 10,000 amperes. This high interrupt capacity helps protect the panel and surrounding wiring from catastrophic failure during severe short‑circuit events.

Is this breaker suitable for outdoor installations?

While the breaker itself is rated for indoor panel use, its corrosion‑resistant construction makes it suitable for panels located in damp or semi‑outdoor environments, provided the panel enclosure meets the required environmental protection standards.

How do I test the GFCI function?

The breaker includes a test button on the front. Pressing this button simulates a ground‑fault condition, causing the breaker to trip. After testing, reset the breaker by moving the toggle back to the “ON” position. Regular testing ensures the device remains functional.
