ABB S202U-Z20A - 20A, 240VAC, 2-Pole, Circuit Breaker

ABB S202U-Z20A is a dependable 20A, 240VAC, 2-pole circuit breaker engineered for reliable overcurrent protection in demanding electrical environments. Designed for panelboards, switchboards, and control panels, it delivers synchronized interruption of both live conductors on a 240V circuit, enhancing safety and protecting attached equipment.

• Current rating: 20 A
• Voltage rating: up to 240 VAC
• Poles: 2-Pole configuration for 240V circuits
• Breaker type: Circuit Breaker

This device is ideal for industrial, commercial, and OEM applications where dependable protection and safe operation in distribution panels and motor control centers are critical. Whether you’re wiring a new panel, upgrading an aging enclosure, or integrating a protective device into compact control cabinets, the S202U-Z20A provides a straightforward, robust solution.

What makes it stand out is the two-pole design that ensures both hot legs on a 240V circuit are disconnected together when the breaker trips. This synchronized shutoff minimizes risk during faults and helps prevent backfeed scenarios that can compromise equipment safety and uptime. Paired with ABB’s engineering rigor, this breaker delivers consistent performance in the field, even under demanding loads.

Use cases and scenarios you’ll encounter with the S202U-Z20A include protecting motors, conveyors, pumps, and other 240V machinery, guarding control circuits in panelboards, and serving as a reliable OEM component in custom electrical assemblies. It’s a practical choice for new installations and as a replacement in existing systems that require straightforward, two-pole protection.

Practical tips for optimal installation: - Install in appropriate distribution panels and control enclosures designed for 2-pole devices. - Use in systems where simultaneous disconnect of both conductors improves safety and compliance for 240V circuits. - Pair with compatible wiring and accessories as recommended by ABB to ensure reliable trip performance and longevity.
