ST-3-AC220V30A-UL 30A Double Pole Hydraulic Magnetic Circuit Breaker Features
- Versatile Dual-Voltage Protection
This double-pole circuit breaker is expertly engineered for robust performance in both DC 80V and AC 240V electrical systems. The two-pole protective device provides synchronized interruption, safeguarding two circuits or a single 240V line with a reliable 3000A breaking capacity. This AC/DC compatible interrupter offers flexible application across diverse electrical setups.
- Internationally Certified Performance
Engineered for global compliance, this electrical safety switch adheres to stringent standards including GB17701, IEC60934, IEC60947-2, and UL1077. The certified circuit protector features a rated insulation voltage of 500V, ensuring enhanced safety and operational integrity. Its conformance to these recognized benchmarks makes it a trusted component for critical installations.
- Enhanced Operational Endurance
Designed for sustained reliability, this industrial-quality circuit breaker offers an impressive mechanical lifespan of 10,000 operations. The durable dual-toggle switch also ensures a significant electrical lifespan of 6,000 operations, providing consistent protection over extended use. A rated impulse withstand voltage of 4000V further underscores its resilience against electrical stresses.
- Broad Environmental Adaptability
This heavy-duty circuit protector is constructed to function dependably across a wide operating temperature range, from -40°C to +85°C. The resilient safety interrupter performs optimally at altitudes up to 2000 meters and in environments with relative air humidity up to 95%. Its design is suited for locations free from explosive atmospheres and corrosive elements.
- Predictable Overcurrent Response
Utilizing a Z2/J2 characteristic trip curve, this protective toggle breaker delivers precise and predictable tripping action under overload conditions. For example, the safety cut-off device is designed to interrupt the circuit within 3 to 70.0 seconds when subjected to 135% of its rated current. This calibrated trip mechanism ensures tailored protection for connected electrical systems and equipment.
