## Description

CHTAIXI DC Miniature Circuit Breaker, 2 Pole 1000V 32 Amp | DIN Rail Mount Isolator for Solar PV System, Thermal Magnetic Trip DC Disconnect Switch C32: desertcart.com: Tools & Home Improvement

Review: Great DC Breaker - I used this 32A 2-pole DC breaker as a disconnect between my solar panels and charge controller, and it’s been a solid addition to my system. The DIN rail mounting made installation quick, and the terminals held my wiring securely with no issues. The switch has a firm, positive feel when turning it on and off, and having both overload protection and an easy way to isolate the PV array adds peace of mind when working on the system. It feels well-built and is compact enough to fit neatly inside my electrical enclosure. If you’re building or upgrading a solar setup and need a reliable DC disconnect, this breaker is a great value and performs exactly as expected. Highly recommended.
Review: Great Protection - I installed 3 of these almost a year ago. I have had no issues with PV voltages from 3 solar arrays, all putting out up to 500 Vdc at times. I recently rewired a PV array of 12 panels. Made the mistake of inverting the polarity. When I turned on the breaker, it smoked, bigtime! then all was silent. No fire, no melting of the breaker. I measured the voltage at the input and realized the polarity was reversed. My bad! I disabled the voltage at the panels, rewired correctly, and connected to a new breaker. All worked well. My biggest point with this review is, even though the breaker fried, it kept the reverse voltage of over 400 Vdc from getting to the solar inverter and causing hundreds to thousands of dollars in damage. The breaker not only will trip if the amperage is exceeded, but also protects from reversed Vdc. Very thankful!

## Features

- FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation.
- FAST TRIP: The electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit.
- ARC EXTINGUISHING: DC arc extinguishing is more difficult than AC. This DC mini circuit breaker has a magnetic system to assist arc extinguishing.
- APPLICATION: Used in DC power system, ship electric power system, solar photovoltaic system, or other DC system.
- INSTALLATION: Screw clamp wires, 35mm DIN rail mount.
