Sprecher + Schuh KTA5-32A-4.0A Breaker
It is a compact thermal-magnetic circuit breaker designed for industrial electrical systems, providing overload and short-circuit protection. Suitable for AC/DC distribution cabinets, mechanical equipment and automation control panels, it complies with international safety standards to ensure reliable circuit disconnection.
Core Features
✅ Dual protection mechanism:
Thermal tripping: responds to overload current (4.0A rated value, ±20% accuracy).
Magnetic tripping: Instantaneous action on short-circuit current (32A breaking capacity).
✅ Industrial-grade design:
Rated current: 4.0A, frame current 32A (maximum support).
Voltage range: AC 400V / DC 250V (multi-purpose compatible).
Number of poles: 1P (single pole), DIN rail installation (compliant with EN 60715 standard).
✅ Safety and durability:
Breaking capacity: 6kA (IEC 60947-2 certified).
Material: flame-retardant housing (UL94 V-0), resistant to high temperature and arc.
Protection level: IP20 (need to be used with distribution box).
✅ Convenient operation:
Manual lever switch, the status is clearly visible.
Standard modular width: 17.5mm, saving space.
