Product Overview

The DZ47-63 series is a compact miniature circuit breaker developed for single-phase AC 110V/240V, 50/60Hz distribution systems. It is designed to protect branch circuits, electrical equipment, lighting lines, control panels, and small power distribution boards from overload and short-circuit faults. With a 2-pole structure, C-curve tripping characteristic, and rated current options from 6A to 63A, this breaker is suitable for residential, commercial, and light industrial electrical installations that require dependable circuit isolation and daily switching control. The product is commonly used in North American style distribution systems and other projects where 110V or 240V single-phase protection is required.

Built with a flame-retardant insulated housing, thermal-magnetic trip mechanism, and screw terminal connection, the breaker helps reduce equipment damage and fire risk caused by abnormal current conditions. The handle clearly indicates ON, OFF, and TRIP positions, allowing users and electricians to quickly identify circuit status during inspection or maintenance. The product complies with IEC 60947-2 and carries CE certification, making it a practical choice for OEM panels, electrical cabinets, small machinery, and standard power distribution applications.

Key Features

110V/240V Single-Phase Protection: Designed for AC single-phase circuits and suitable for line protection in North American style electrical systems.
C-Curve Trip Performance: The C type trip curve supports most general loads and provides reliable response under overload or short-circuit conditions.
2-Pole Circuit Isolation: The 2P design can disconnect both poles at the same time, improving safety during maintenance and fault isolation.
6kA Breaking Capacity: Rated 6kA short-circuit breaking capacity supports dependable protection for standard residential and commercial circuits.
Clear Status Indication: The handle position shows ON, OFF, and TRIP states, helping technicians identify the circuit condition quickly.
Safe Terminal Connection: Screw terminals support AWG 18 to AWG 8 copper conductors with a recommended tightening torque of 2.5 N.m.
