TB330 | Circuit Breaker | 30A | 3-Pole | 240V

Introducing the TB330, a rugged industrial circuit breaker engineered for reliability in demanding electrical systems. With a 30A rating across 3 poles at 240V, this unit delivers robust protection for 3-phase equipment while keeping installation straightforward for maintenance, retrofit, and replacement projects.

Key advantages that set TB330 apart:

• Precise overcurrent protection for 3-phase circuits up to 240V, helping prevent damage to motors and downstream gear.
• Three-pole design enables simultaneous switching and protection of all three live lines, ideal for dedicated industrial machinery and panels.
• Direct reference part number TB330 is the best compatibility reference, simplifying sourcing and replacements.
• Maintenance-friendly and retrofit-ready, designed to slot into existing panels where matching specs are required.

Before you order, note the importance of fit and ratings: Confirm fit and ratings before ordering. Using a like-for-like TB330 ensures panelboard alignment, trip characteristics, and mounting compatibility, reducing downtime and guesswork.

Who should consider this circuit breaker? Engineers, facility managers, and skilled technicians handling aging electrical infrastructure or upgrading panel protection for 3-phase equipment. It’s well-suited for motor drives, HVAC systems, conveyors, presses, and other industrial processes where reliable 240V, 3-pole protection is non-negotiable.

Practical tips for use:

• Match this 30A, 3-Pole, 240V unit to systems calling for TB330 or equivalent three-phase protection with identical trip characteristics.
• Keep the part number TB330 as your compatibility reference when sourcing replacements or retrofits.
• Inspect panel labeling and bus configurations to ensure straightforward installation and safe operation.
