Entrelec compact contactors, small contactors, control relays, and supporting system components

The Entrelec brand’s electrical control product catalog covers three major categories of products: compact contactors, small contactors, control relays, and supporting system components. All products comply with international/national standards such as VDE 0106 and IEC 309-1, and have advantages such as high contact reliability (ENTRELEC-SCHILE dual auxiliary contacts), safety protection (anti touch design, 400V safety isolation), and easy installation (snap on/screw on installation); The product is divided into two types according to the driving type: AC/DC, with coil voltage covering 12V~600V (including color coding distinction), suitable for 2.2kW~18.5kW three-phase motors and various resistance/inductance loads, equipped with auxiliary contact modules, coil suppressors, timers and other components, which can meet the needs of multiple scenarios such as industrial control and building automation. The document also provides complete models, order numbers, parameter specifications and installation instructions.

Overall positioning and core advantages of the product

Brand and standards: The product complies with international and German standards such as VDE 0106, IEC 309-1, DIN EN 50011/50012, and meets safety and reliability standards.

Core strengths

High contact reliability: Adopting ENTRELEC-SCHILE dual auxiliary contacts, the contact reliability is 1000-10000 times higher than standard contacts, and some products have a forced disconnection design.

Safety protection: The terminals comply with VDE 0106 Part 100 anti touch standards, and the coil and contacts are safely isolated up to 400V AC to avoid the risk of electric shock.

Easy installation and wiring: Supports snap on and screw installation, pre opened terminal clamp design, and accelerated wiring with positive and negative screws; Some products support 35mm rail installation.

Strong universality: The AC coils are all 50/60Hz dual frequency compatible, with coil voltages covering 12V~600V, and are distinguished by color coding according to the IEC 309-1 standard (such as 24V AC being purple and 230V AC being blue).

Core product classification and key specifications

According to product types, it can be divided into four categories, with core parameters as shown in the table below:

Control relay KH series AC/DC/interface type rated thermal current 10A coil power consumption 1.8-4.5W, with LED indication 3NO1NC~4NO programmable controller interface, low signal switching

Note: All products are labeled with the complete order number (such as DL 4K-10 order number 1 366 001..), and some models are distinguished by “with/without integrated coil suppressor”.

Coil voltage and color coding

The coil voltage covers 12V~600V, and there are corresponding models for AC/DC drivers. The color coding standard is as follows:

Coil voltage AC color coding DC color coding voltage code standard voltage (commonly used)

12V~32V Purple Green 04~10 24V (AC/DC), 36V (AC)

36V~48V green/white green 11~15 42V (AC), 48V (DC)

60V~127V Yellow Green 19~29 110V (AC/DC), 120V (AC)

208V~240V Blue Green 38~43 230V (AC), 220V (DC)

380V~440V red -61~65 380V (AC), 400V (AC)

500V~600V Black -69~73 500V (AC), 600V (AC)

Supporting system components

All products come with dedicated supporting components to meet expansion and protection needs. The core components are as follows:

Auxiliary contact module

Type: 2-pole/4-pole, front mounted (Hi/Li series)/side mounted (S 11/S 20 series), with/without manual operation plunger.

Example order numbers: Hi-11 (3 369 011 01), S 11 (3 368 002 01).

Coil suppressor

Classification: RC type (for AC, such as RC-K 01), diode type (for DC, such as DK-01), varistor type (for AC/DC, such as V-K 01).

Function: Suppress transient voltage, protect electronic components, some with LED indication.

Timer component

Pneumatic (PZ series): Delay 0.1~180s, supports delayed on/off, snap on installation.

Modular (ZM-K/YZ-K series): Delay of 0.2~250s, compatible with star delta start and panel control.

Other components

Mechanical Interlocking (MV-e): Side mounted, used for safety interlocking of reversible contactors.

Star Triangle Startup Module (YZ-K): 24-240V AC, with a delay of 1.5-30s.

Installation and adaptation instructions

Installation method: Supports buckle type (rail/panel) and screw type fixation, and some products can be stacked with installation components.

Terminal type: The control relay provides three terminal options – screw terminal (S suffix), quick connect terminal (F suffix, 2.8mm/6.35mm), and solder pin terminal (L suffix, 1.7mm).

Thermal overload relay adaptation: Compact contactors are compatible with the M 23 K/M 40 K series, and small contactors are compatible with the M 06 series (0.1~11.5A).

Applicable scenarios: industrial control (motor start stop), building automation (air conditioning/ventilation), resistive loads (heaters/lighting fixtures), inductive loads (valves/couplings).
