12V-110V DC Miniature Circuit Breaker CHTAIXI 60A 2‑Pole Protector

Description

Product Overview

The CHTAIXI 60A 2‑Pole Miniature Circuit Breaker is engineered to deliver dependable protection for a wide range of direct current (DC) applications, from residential solar photovoltaic (PV) installations to recreational vehicle (RV) power systems and portable battery packs. Constructed with a robust thermoplastic housing and high‑quality copper contacts, the breaker offers a compact footprint while meeting rigorous safety standards. Its DIN‑rail compatible design enables seamless integration into standard electrical panels, and the screw‑clamp terminals accommodate a variety of wire gauges for flexible wiring options.

Designed for voltage ranges of 12V to 110V, this breaker provides a magnetic trip response that activates instantly when a short circuit occurs, minimizing the risk of equipment damage and fire hazards. The Curve B characteristic ensures the magnetic trip range is 4‑7 times the rated current, delivering precise protection tailored to the needs of high‑current DC loads. With a rated breaking capacity of 60A, the device can safely interrupt fault currents while maintaining long‑term reliability.

Additional specifications include a compact size of 2.96 x 1.41 x 3.26 inches, a lightweight profile of 6.88 ounces, and compliance with IEC standards for miniature circuit breakers. The product is backed by a strong customer rating of 4.7 out of 5 stars based on 245 reviews, reflecting its performance and durability in real‑world installations.

Usage

Ideal for solar PV arrays, the breaker can be installed on the DC side of charge controllers to protect inverter inputs and battery banks from over‑current events. In RV applications, it serves as a critical safety component for on‑board power distribution, safeguarding lighting, appliances, and auxiliary systems that draw significant current from the vehicle’s battery pack.

Beyond stationary installations, the breaker is suitable for electric mopeds, portable power stations, and any DC system requiring reliable overload and short‑circuit protection. Its fast magnetic trip feature ensures that sudden spikes, such as those caused by motor start‑up or accidental wire shorting, are cleared within milliseconds, preserving both the power source and downstream devices.

Installation is straightforward: mount the breaker onto a standard 35 mm DIN rail, then connect the incoming and outgoing conductors using the provided screw clamps or M5 wire lugs. The clear labeling on the unit assists technicians in quickly identifying the rated current and pole configuration, reducing installation time and potential errors.

FAQ

What voltage range does this breaker support?

The breaker is rated for DC voltages from 12V up to 110V, making it suitable for a variety of low‑voltage power systems, including solar arrays, RV battery banks, and portable DC devices.

Can this breaker be used for AC applications?

No. This model is specifically designed for DC circuits. Using it on AC systems could result in improper tripping characteristics and is not recommended.

How does the magnetic trip differ from the thermal trip?

The magnetic trip reacts instantly to short‑circuit currents, opening the circuit within milliseconds. The thermal trip, on the other hand, responds to prolonged overloads by heating a bimetallic element that bends to break the circuit, providing protection against sustained overcurrent conditions.

Is the breaker compatible with standard 35 mm DIN rails?

Yes, the unit is designed to snap onto a standard 35 mm DIN rail, allowing easy installation in most electrical panels that follow IEC mounting standards.

What warranty does CHTAIXI offer for this product?

CHTAIXI provides a one‑year limited warranty covering manufacturing defects. For detailed warranty terms and support contact information, please refer to the product documentation or contact our customer service team.
