HEATINGVARIOUSMFG-GENERIC PLMU11 Voltage Monitor

Product Description

The Littelfuse PLMU11 is a voltage monitoring relay designed for 3-phase motors and sensitive loads. It continuously monitors the voltage across all three phases, using a microcontroller to detect conditions such as undervoltage, overvoltage, phase loss, voltage unbalance, and phase reversal. This model provides effective protection even in scenarios where regenerated voltages occur.

• Protects 3-phase motors and sensitive electrical loads.
• Microcontroller detects various voltage issues.
• Universal voltage range from 200 to 480 VAC.

Product Highlights

The PLMU11 features a versatile and standard base connection, enabling it to serve as a replacement for many competitive models.
