32A 2-Pole Chint DC Circuit Breaker (12V/24V/48V DC)

Overview

Protect your solar PV array, charge controller, and battery bank circuits with our 32A 2-Pole DC Circuit Breaker. Engineered specifically for direct current (DC) power systems, this thermal-magnetic circuit breaker automatically trips to isolate the electrical path whenever current exceeds safe thresholds, shielding sensitive solar electronics from overcurrent hazards and short circuits.

Featuring a dual-pole design, it disconnects both positive and negative legs simultaneously in two-wire DC circuits, providing a safe, centralized point of isolation during routine system maintenance. Compact and lightweight, it fits seamlessly onto standard DIN-rail setups across residential off-grid systems, solar combiner boxes, and battery storage banks.

Key Highlights

• Dual-Pole Overcurrent Protection: Disconnects both circuit legs simultaneously to prevent severe overloads and dead short-circuits.

• Thermal-Magnetic Tripping: Combines quick magnetic response for sudden short circuits with thermal protection against sustained current overloads.

• Multi-Voltage Compatibility: Engineered to handle low-voltage DC setups, including 12V, 24V, and 48V DC battery lines and solar strings.

• Compact DIN-Rail Form Factor: Standardized enclosure measuring 90 x 50 x 60mm for clean, organized installation inside distribution boards and combiner boxes.

• Essential Off-Grid Safety: Protects charge controllers, low-voltage inverters, and battery banks from catastrophic electrical stress.
