Frequently Asked Questions (FAQ)

Q: What is the primary difference between the MS and MO series?

The MS series provides comprehensive thermal-magnetic protection designed to protect against both overloads and short circuits. The MO series features magnetic-only trip protection, primarily intended for short-circuit protection when paired with external thermal overload devices.

Q: Does the MS132 circuit breaker include phase failure protection?

Yes, the MS132 manual motor starter comes standard with built-in phase failure sensitivity, ensuring safe operation and motor disconnection in the event of an unbalanced power supply or lost phase.

Q: Can the handle be locked directly without auxiliary accessories?

Yes, the MS132 series features a lockable rotary handle that can be locked directly in the OFF position using a padlock, requiring no additional locking brackets or accessories.

Q: What is the operating ambient temperature range for this series?

The device operates reliably within an ambient air temperature range of -25°C to +60°C, providing compensated thermal protection across fluctuating thermal conditions.

Q: What is the standard module width of the MS132 unit?

The MS132 features an ultra-compact modular width of 45 mm, enabling space-saving installation on standard DIN rails within industrial control panels.
