Wet Contact (Powered Contact) Example: Dry Contact (Potential-Free Contact) Example: Key Differences: Feature Dry Contact Wet Contact Power Source External circuit Internal source of relay Voltage Supply No voltage on contacts Voltage present on contacts Application Control external load Trigger… Continue Reading →

MCB vs MCCB: Key Differences Explained

MCB (Miniature Circuit Breaker) is an automatically operated electrical switch that protects circuits from overcurrent and short circuits. It is mainly used in low-voltage applications such as residential, commercial, and light industrial installations. Working Principle of MCB: Applications of MCB:… Continue Reading →

Understanding MCB Alarm Signals: Causes and Solutions

Miniature Circuit Breakers (MCBs) play a crucial role in electrical protection by automatically disconnecting a circuit when an overload or short circuit occurs. However, sometimes MCBs trigger alarm signals, alerting users to potential issues. Understanding the causes behind these alarms… Continue Reading →

Why We Trigger Alarm Signals from MCB to DI Module: A Complete Explanation

When an MCB detects an overload or short circuit, it must immediately react to cut off power and protect the system. However, it is not enough for the MCB to just interrupt the current; there needs to be a feedback… Continue Reading →
