Product description
Current monitoring relay M3056 AC (NC contact opening, adjustable 0,2-30 A)
Are you looking for a reliable, accurate and completely autonomous AC current monitoring solution? The M3056 current monitoring relay with Normally Closed (opening contact) function has been specially designed for efficient protection of electrical installations, monitoring of machine operation and automation of industrial and domestic systems.
This device works on the principle of non-contact inductive sensing. It uses an internal transformer for measurement, so that the phase conductor to be monitored can simply be threaded through a 10 mm diameter hole in the body of the device. No complicated wiring in series or interruption of the power cable is required. A major advantage is that the device does not require an external power supply, as it is powered inductively directly from the current passing through the receiver.
Working principle:
Use the precision multi-turn potentiometer to easily set the desired current threshold (in the range of 0.2 to 30 A AC).
Current overshoot: As soon as the flowing current exceeds the threshold you set, the output contacts K1-K2 open immediately (NC contact opening logic).
Current drop: If the current drops below the set limit, the K1-K2 contacts return to their original state and remain compact (closed).
Main advantages of the M3056 current relay:
-Completely autonomous operation: it operates without any auxiliary power supply - saves space in the cabinet and simplifies wiring.
-High accuracy and speed.
-Safe inductive sensing: Galvanic isolation of the measured circuit from the switching contact ensures maximum safety.
High overload resistance: the relay can handle short-term maximum overloads of up to 100%.
-Low hysteresis: Very stable switching due to low hysteresis (? 2%), which prevents unwanted contact oscillation at values close to the set limit.
Technical parameters:
-Model: M3056
-Output type: Normally Closed (NC), terminals K1-K2
-AC input current range: 0.2 to 30 A AC
-Threshold setting: Multi-turn potentiometer
-Power supply: No external power supply (inductive from the measured conductor)
-Nominal contact load: ? 0.3 A at 240 V AC/DC Contact resistance (K1-K2): 4 Ohm.
-Leakage current: ? 0.1 A
-Measuring accuracy: 1%
-Hysteresis: ? 2%
-Response time: ? 200 ms
-Wire hole diameter: 10 mm
-Protection level: IP30
-Operating temperature: -20? to +60?
-Dimensions: 65 × 25 × 47 mm
Provide your wiring and machinery with professional autonomous supervision. With the M3056 current detection relay you get a precise and reliable overload guard that does not need a watt of external power to do its job.
