ABB S3H - 160A, 690VAC, 3-Pole, Circuit Breaker

When you need reliable, three-phase overcurrent protection for demanding industrial environments, the ABB S3H 160A, 690VAC, 3-Pole circuit breaker is built to perform. Designed for modern distribution panels, switchboards, and control panels, this unit delivers balanced protection across all three phases, helping prevent damage from overloads and short circuits in motor drives, conveyors, presses, and other equipment.

Core specifications

• Current rating: 160A
• Voltage rating: 690VAC
• Poles: 3-Pole
• Breaker type: Circuit Breaker

Why this ABB S3H breaker stands out

• Three-pole design provides synchronized protection for all three phases, minimizing the risk of unbalanced loads and partial system faults.
• 690VAC rating expands its suitability for higher-voltage distribution environments and motor control centers that require robust protection without compromising performance.
• Built to integrate with standard industrial panels, the S3H supports dependable operation in panelboards, switchboards, and control panels used in manufacturing, processing, and OEM equipment.
• Industrial-grade construction and ABB reliability mean fewer nuisance trips and longer service life in challenging environments.

Best-fit scenarios

The ABB S3H 160A 690VAC 3-Pole breaker is ideal for:

• Motor control centers and equipment lines where three-phase protection is essential.
• Distribution panels in factories, warehouses, and processing facilities that demand high reliability.
• OEM equipment enclosures that require compliant, scalable overcurrent protection.

Practical considerations and tips

• Ensure your system voltage aligns with the 690VAC rating and that the breaker’s trip curve suits your application’s protection needs (consult your electrical design documents for coordination and selectivity).
• Use within standard panelboard or switchboard configurations that accommodate 3-pole devices and support coordinated protection with upstream and downstream devices.
• For installations requiring remote signaling or trip-interlock, explore compatible accessories offered for the ABB S3H family.

Equip your electrical distribution with ABB S3H 160A 690VAC 3-Pole circuit protection and keep three-phase systems safe, stable, and ready for demanding industrial operation.
