A-B 188-K4D030 Miniature Circuit Breaker 3A, For Industrial Control
The Allen-Bradley 188-K4D030 Miniature Circuit Breaker delivers precision overcurrent protection for industrial control systems. Engineered with a space-saving form factor, this 3-pole circuit breaker features a Type B trip curve for optimal response to short circuits. Its panel-mount design and rugged construction withstand demanding industrial environments while maintaining compliance with CE, UL, and IEC safety standards.
Key Specifications:
Brand: Allen-Bradley
Model: 188-K4D030
Rated Current: 3A
Protection Class: Type B Trip Characteristic
Poles: 3
Certifications: CE, UL, IEC 60898-1
This industrial-grade circuit breaker incorporates a precision-calibrated magnetic trip mechanism that disconnects circuits within milliseconds during overload or short-circuit events. The thermally stabilized bimetal strip ensures consistent performance across temperature fluctuations (-25°C to +55°C). Gold-plated contacts minimize resistance and prevent arc erosion, extending operational lifespan beyond 20,000 cycles.
Installation efficiency is enhanced through tool-free DIN rail mounting (EN 60715 compliant) and clear visible trip indicators. The flame-retardant polycarbonate housing (UL94 V-0 rated) provides arc containment while offering IP20 finger protection. Ideal for motor control centers, PLC cabinets, and distribution panels in manufacturing plants and critical infrastructure.
