Q1B330 - 30 Amp Circuit Breaker

Q1B330 - 30 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, getting the details right matters. The Q1B330 is a 30-amp, 3-pole thermal-magnetic circuit breaker with a bolt-on connection. It is rated 10 kA I.C. at 240 VAC and is designed for applications requiring the Type Q1B configuration. This breaker measures 6.38 inches high, 2.25 inches wide, and 2.31 inches deep and requires six spaces. That makes checking the available space, mounting style, and electrical ratings especially important before installation. For maintenance and repair of compatible legacy equipment, the Q1B330 provides the familiar form, fit, and function needed when matching an existing breaker. It's a straightforward choice when your application specifically calls for these ratings and dimensions, and these products are built to last when properly selected, installed, and maintained.

Key Features and Benefits

• 30-amp rating for applications designed around this specific current rating.
• Three-pole configuration for compatible three-pole circuits.
• Bolt-on mounting provides the connection style required by equipment designed for Q1B breakers.
• Therma-magnetic operation responds to both sustained overloads and short-circuit conditions.
• 10 kA I.C. at 240 VAC provides the specified interrupting rating for the breaker.
• Type Q1B design helps make identification easier when matching an existing breaker.
• Requires six spaces, an important detail to check when confirming physical compatibility.
• A practical option for maintenance and functional replacement in compatible legacy electrical equipment.
