12V-110V DC Miniature Circuit Breaker CHTAIXI 15A 1-Pole Magnetic

Description

Product Overview

The CHTAIXI 15A 1‑Pole DC miniature circuit breaker is engineered to provide dependable protection for a wide range of low‑voltage direct current applications. Constructed from high‑grade copper contacts and a robust thermoplastic housing, the breaker delivers consistent performance even in harsh environments. Its compact dimensions—2.96 x 0.7 x 3.26 inches and a weight of just 3.52 ounces—make it ideal for space‑constrained panels and enclosures. The device operates across a voltage range of 12V to 110V, covering common battery, solar photovoltaic, and recreational vehicle power systems. Featuring a magnetic trip curve (Curve B) that activates at 4‑7 times the rated current, the breaker swiftly clears short‑circuit conditions while the thermal element guards against prolonged overloads. Installation is straightforward thanks to versatile mounting options: a 35 mm DIN‑rail slot for panel mounting or a surface‑mount configuration for direct board attachment. Wire connections are secured with screw‑clamp terminals or optional M5 wire lugs, ensuring a solid, low‑resistance path for current flow.

Usage

Designed for versatility, this miniature circuit breaker excels in solar power installations, where it protects charge controllers, inverters, and battery banks from over‑current events. In recreational vehicles, the breaker safeguards lighting circuits, entertainment systems, and auxiliary power outlets, providing peace of mind on the road. It is also suitable for electric mopeds, marine applications, and any DC system that demands reliable fault interruption. The breaker’s 15 A rating accommodates typical residential solar arrays and RV battery banks, while the available range of sizes—from 6 A up to 60 A—allows users to select the exact protection level required for their specific load. Its magnetic arc‑extinguishing capability reduces the risk of arcing damage during sudden short circuits, a critical feature for high‑current DC environments where arc flash hazards are a concern.

Because the breaker can be mounted on a DIN‑rail, it integrates seamlessly into standard distribution panels, simplifying wiring layouts and reducing clutter. For custom enclosures or retrofit projects, the surface‑mount option provides flexibility without compromising safety. The device’s low profile also means it can be incorporated into portable power kits, enabling field technicians to quickly add circuit protection to temporary setups.

FAQ

What voltage range does this breaker support?

The breaker is rated for direct current voltages from 12 V up to 110 V, making it suitable for most battery, solar, and RV power systems.

Can I install this breaker on a standard DIN‑rail panel?

Yes, the breaker includes a 35 mm DIN‑rail mounting clip that fits standard panels, allowing quick snap‑in installation without additional hardware.

How does the magnetic trip curve protect my equipment?

When a short‑circuit occurs, the magnetic element detects the rapid rise in current and trips the breaker within milliseconds, extinguishing the arc and preventing damage to downstream components.

Is the breaker suitable for marine environments?

The breaker’s sealed housing provides resistance to dust and moisture, making it appropriate for marine and outdoor applications where exposure to the elements is a concern.

What sizes are available if I need a different current rating?

In addition to the 15 A model, the product line offers sizes ranging from 6 A to 60 A, allowing you to select the exact protection level required for your specific load.
