Heschen DC 250 Amp Circuit Breaker, 550V Battery Disconnect Switch, Solar

• [HEAVY-DUTY SOLAR DISCONNECT] Specifically designed for demanding DC applications. This 2-Pole 250 Amp Molded Case Circuit Breaker operates securely at a rated voltage of DC 550V. It is the perfect reliable main isolator switch for your solar panels, off-grid PV arrays, and home battery storage systems
• [THE ANATOMY OF SAFETY] Built with commercial-grade internals for extended durability. Featuring pure copper braided straps to prevent overheating, premium silver-plated dynamic contacts for ultra-low resistance, and an 8-blade arc extinguishing matrix that rapidly suppresses severe short-circuits
• [15kA SURGE PROTECTION & WIRING] Delivers a reliable 15kA rated ultimate short-circuit breaking capacity (Icu). The left/right polarity is non-polar. However, for utmost safety and to maintain the maximum 15kA capacity, a Top-Feed connection (LINE at the top, LOAD at the bottom) is strictly required
• [BUILT FOR EXTREME ENDURANCE] Compliant with rigorous IEC 60947-2 standards. With a high insulation voltage (Ui) of 1000V, impulse withstand voltage (Uimp) of 8kV, and a wide operating temperature range of -5°C to +40°C, it provides steadfast protection for your expensive inverters and charge controllers
• [COMPLETE KIT & EXACT DIMENSIONS] Precision-engineered for your enclosure. Dimensions: 6.50" (H) x 3.38" (W) x 4.02" (D). The package includes the HSM1PV-250 MCCB, 2 flash barriers, mounting screws, and a hex Allen wrench for secure installation
