Key specifications

• Current rating: 90 A
• Poles: 3
• Voltage rating: up to 600 V
• Part number: CLE63B090

Why this 3-pole, 90 A configuration matters

For three-phase systems, a 3-pole circuit breaker like the CLE63B090 provides coordinated protection across all phases. This helps ensure consistent disconnection during overloads or fault conditions, reducing the risk of unbalanced loads and potential damage to motors and other equipment. The 90 A rating is ideal for mid-size feeders and motors in many industrial setups, offering protection without unnecessary trips in properly sized circuits.

Ideal use cases

• Industrial control panels and motor control centers that run on three-phase power
• Commercial distribution boards safeguarding feeders to pumps, conveyors, fans, and HVAC drives
• Panel upgrades or replacements where a reliable 3-pole, 600 V protection device is required

Installation and compatibility

Use this CLE63B090 circuit breaker with Siemens panels that accept CLE-series devices. Confirm that your system voltage and load characteristics align with a 3-pole, 90 A, 600 V protection device. For optimal performance and serviceability, reference the CLE63B090 datasheet and your panel’s compatibility guide when sourcing replacements or performing upgrades.

Benefits you’ll notice

• Coordinated, three-phase protection that helps safeguard motors and three-phase circuits
• Clear, traceable part identification (CLE63B090) for fast replacements
• Robust performance in environments that operate at up to 600 V
