Breaker Types

• DC breakers for solar strings and battery banks (150VDC to 600VDC)
• AC breakers for panels, sub-panels, and transfer switches
• Miniature breakers (MCB) in DIN rail format
• Trip curves – C, D, and Z for different load types
• Combiner box breakers for multi-string arrays
• Breaker accessories – handles, locks, and shunt trips

Proper breaker sizing is critical for system safety. DC breakers for solar must be rated for the array's voltage and current, while battery breakers must handle high continuous and surge currents. Our breakers are UL-listed and rated for the demanding conditions of solar and energy storage installations.
