What is ABB MS116-6.3?
The ABB MS116-6.3 is part of ABB's classic MS116 series manual motor starter, referred to as MPCB in the industry. It has an adjustable current range of 4.0～6.3A and comes in a 3-pole design. One single device provides motor start-stop control, overload protection, short-circuit protection and phase loss protection, perfectly suited for different low-power three-phase motors.
Compact in size with just 45mm width, it supports standard DIN rail mounting for straightforward installation. The ABB MS116-6.3 is frequently used on automation machinery, conveyor systems, water pumps, fans and OEM control cabinets. It remains a widely chosen motor protection switch for industrial control cabinet applications.
Why Choose ABB MS116-6.3?
1.Integrated Thermal & Magnetic Protection
Internal thermal trip for overload protection and magnetic trip for short-circuit protection. Built-in phase loss protection avoids motor damage from phase failure.
2.Adjustable Current Design
Front adjustment knob for direct current setting from 4.0~6.3A.
3.Reliable Isolation Function
Main circuit isolation function. Knob marked ON/OFF for safe power cut during maintenance.
4.Modular Expandable Design
Compatible with auxiliary contacts, shunt trips, undervoltage releases and other accessories.
ABB MS116-6.3 Application Scenarios
The ABB MS116 series motor protection switches cover a wide range of applications. The ABB MS116-6.3, rated for 4.0~6.3A, is designed for small three-phase motors with rated current between 4 and 6.3A. It works well on conveyor lines, belt conveyors, water pumps, fans and HVAC units, as well as packaging machinery, woodworking equipment, agricultural automation devices and small air compressors. It is also a popular MPCB motor protection circuit breaker for machinery OEMs and complete control cabinet assembly.
Selection Tips
Improve efficiency
1.The primary reference for selection is the rated current of your motor. The ABB MS116-6.3 has an adjustable range of 4.0~6.3A, suitable for 2.2kW three-phase motors at 380V.
2.The setting current needs to match motor parameters. Choosing an oversized model blindly will weaken overload protection.
3.If your motor rated current is outside this range, check other models in the MS116 series: MS116-2.5, MS116-4, MS116-10, MS116-16.

FAQ
Q1: Does the ABB MS116-6.3 come with built-in phase loss protection?
A1: Yes. All models of the MS116 series are equipped with phase loss sensitive protection, which detects phase failure conditions and prevents motor burnout.
Q2: Can the ABB MS116-6.3 directly control motor start and stop?
A2: Yes. As an integrated manual motor starter, it works without an additional contactor and provides both start-stop control and protection for small motors.
Q3: What type of rail is required for installation?
A3: It adopts snap-on mounting on standard 35mm DIN rail, compatible with ordinary widely available rails.
Q4: How can I place an order or apply for bulk purchase discounts?
A4: Send your required order quantity via email to Irene8866@163.com, or leave us a message on WhatsApp (+86 18950163907). We will reply within 24 hours with formal quotation and stock confirmation.
