1734-MB product details

Information about the AB 1734-MB module is as follows:

Scope of application:

Mainly suitable for AC 50/60Hz, rated operating voltage 230V/400V and below, rated current to 63A circuit.

It is mainly used for overload and short circuit protection of electrical lines and equipment in modern buildings, and is also suitable for infrequent operation and isolation of lines.

Structural features:

It is composed of plastic shell, operating mechanism, contact arc extinguishing system, tripping mechanism, etc.

The shell is made of special plastic with high flame retardant and high strength, which has strong impact resistance and light weight.

The parts of the operating mechanism are made of high-strength plastic products, which are sensitive and reliable, and the moment of inertia is low.

How it works:

When the short circuit, the magnetic field generated by the large current overcomes the reaction spring, the release device pulls the operating mechanism to act, and the switch is tripped instantaneously.

When the overload, the current becomes larger, the heat is intensified, the bimetal sheet deformation to a certain extent to promote the mechanism action, the greater the current, the shorter the action time.

Other features:

The contact arc extinguishing system uses the arc guide Angle and the aisle chamber, and has significant current limiting characteristics.

There is an electronic circuit breaker, the use of transformer to collect the current of each phase, compared with the set value, when the current is abnormal, the microprocessor sends a signal, so that the electronic trip to drive the operating mechanism action.

Data configuration:

Data configuration is required through a computer or industrial computer and configuration software.

The data configuration process includes the steps of connecting devices, opening configuration software, setting communication parameters, selecting data items, configuring data, saving configurations, and testing configurations.

Product application background:

With the popularity of PC control schemes, PC-based control systems are gradually accepted by manufacturers and adopted in some production.

AB 1734-MB module as a part of industrial automation, its intelligent design ADAPTS to the current development trend of industrial automation.

Alternative products:

Alternative brands include ABB RLM01 (Order number: 3BDZ000398R1).

Other features:

The module also has the function of PROFIBUS DP protocol field bus redundant link module, which can realize the mutual conversion of single bus and redundant double bus.
