Product Overview
The DELIXI CDM3-630H/3300 molded case circuit breaker is a high-performance 3-pole air switch designed for industrial power distribution systems. With a compact structure and 400A current rating, it provides reliable overload and short-circuit protection for electrical equipment. The breaker operates stably under AC690V voltage conditions, featuring 85kA breaking capacity for rapid fault current interruption. Its front-mounted wiring terminals and direct-operated handle ensure easy installation and maintenance. 1413
Key Features
This MCCB incorporates thermomagnetic trip mechanism that delivers precise protection by monitoring load current variations. The robust engineering plastic housing offers excellent flame resistance and mechanical strength. Silver-alloy contacts with low resistance and arc-resistant properties significantly extend service life. The breaker supports both vertical and horizontal mounting orientations, while modular design allows integration of auxiliary contacts and shunt releases for functional expansion. 2915
Technical Specifications
Rated operational voltage AC400V, insulation voltage 800V, and impulse withstand voltage 8kV. The 3-pole breaker features 630A frame current with adjustable settings from 10A to 630A. Mechanical endurance exceeds 20,000 operations, electrical endurance 10,000 cycles. The energy-storage operating mechanism ensures consistent switching performance. Suitable for ambient temperatures ranging from -25℃ to +70℃ under various working conditions. 5716
