Looking for reliable thermal-magnetic motor protection? CHNT motor protectors guard against overload and short circuit simultaneously, priced from ₪104 to ₪116 including VAT. This guide shows how to select the right current range for a motor and install it safely.
Quick Summary
✅ A thermal-magnetic motor protector guards against overload and short circuit at once
💰 Prices range from ₪104 to ₪116 incl. VAT
⚡ Wide current ranges available, from 0.63A up to 25A
🔧 Designed to combine with CHNT's NC1/NC2 contactor series
📦 100KA breaking capacity on most models — strong protection even during severe faults
How to Choose the Right Motor Protection? 🤔
The most important spec is matching the current range to the motor nameplate FLA (Full Load Amps) — the adjustable dial should cover this value. The breaking capacity (typically 100KA) should also be checked to ensure severe fault currents can be cleared safely.
A common mistake is choosing too wide a current range, which reduces protection accuracy — the tightest range that covers the motor FLA should always be selected. Another mistake is ignoring ambient temperature derating, which can shift the effective trip point.
Israeli motors are typically rated 230V/400V, so the FLA in amps on the motor nameplate should always be verified rather than estimated from kW. For a compact panel design, the protector should be paired with a contactor from a matching series.
💡 Pro Tip
Set the trip current dial to the motor actual nameplate FLA, not its kW rating. This prevents both nuisance tripping and inadequate protection.
Installation and Use 🔧
Before installing, power should be switched off and the protector current range confirmed against the motor rated current.
The protector is mounted on the DIN rail or combined directly with a matching contactor, the line and load terminals are connected, and the dial is set to the correct FLA value.
The trip mechanism should be tested periodically, and after an overload trip the root cause should always be checked before resetting. The protection should never be bypassed — it exists to prevent motor burnout.

What is the difference between thermal and magnetic protection?
Thermal protection guards against sustained overload, while magnetic protection trips instantly on a short circuit — combined, they provide complete motor protection.
How is the right current range chosen?
The FLA (Full Load Amps) on the motor nameplate should be checked, and a model whose adjustable range covers that value should be chosen.
Can the motor protector connect directly to a contactor?
Yes, most CHNT models connect directly to NC1/NC2 series contactors to form a compact combined switching unit.
What should be done when the motor protector trips?
The cause of the overload should always be checked before resetting — repeated tripping usually indicates a fault in the motor or load that needs investigation.

Motors can be protected with quality CHNT motor protectors, starting at ₪104 incl. VAT. Order today from stock with fast delivery.
