ABB, Formula DSA, 1SDA06 Molded Case Circuit Breaker 1-Pole 125A, Breaking Capacity 25 kA, Fixed

This moulded case circuit breaker controls and protects single-pole circuits in industrial electrical systems. It is designed for fixed mounting and provides thermal-magnetic tripping suitable for both AC and DC control environments, enabling straightforward overload and short-circuit protection in automation and electrical distribution panels.

• 125A thermal-magnetic rating delivers predictable overload protection
• 25kA breaking capacity limits fault energy during short circuits
• 415V AC rating supports common three-phase distribution voltages
• 125V DC rating allows use in low-voltage DC control circuits
• Front terminals and lever reset provide easy access and operation
• IEC and CE approvals ensure conformity with international standards

• Suitable for motor feeder protection in automation panels
• Ideal for control circuits in industrial machinery installations
• Used with DC control supplies for safety isolation and protection
• Can be used for single-pole protection in distribution boards

It fits a fixed mounting configuration and must be secured to an appropriate panel or mounting rail as part of a dedicated breaker assembly.

The thermal element responds to prolonged overloads while the magnetic element acts instantly on high-magnitude short circuits.

Terminals are positioned at the front to simplify cable connection and reduce access time during installation or maintenance.

The unit is Compact with a narrow width and shallow depth so it occupies minimal lateral and rear panel space.
