BARTEC 07-1511-154D/02 Insert Switch

Overview

The BARTEC 07-1511-154D/02 insert switch is a flameproof switch (Einbauschalter) from the BARTEC 07-1511 series, used as an equipment switch in electrical circuits located in potentially explosive atmospheres. Although the original listing carried the AUMA brand name, the part number 07-1511-154D/02 and the description in the original listing (Insert Switch BARTECH) identify this item as a BARTEC product, and it is supplied and described here accordingly.

Insert switches of the 07-1511 series are mounted into the enclosures of Ex d equipment, where they serve as the local on/off switch for the equipment inside the flameproof housing. The 07-1511-154D/02 is the /02 version of the 154D insert switch, a variant family listed by BARTEC parts suppliers alongside the 07-1511-154D/00.

Engineering & Design

The 07-1511-154D/02 insert switch is designed for installation in flameproof (Ex d) enclosures and is certified for use in explosive atmospheres. The switch is certified to ATEX/UKEX as Ex II 2G Ex db IIC Gb and to IECEx as Ex db IIC Gb, with a mining version certified as Ex db I Mb, per the official BARTEC operating instructions.

The switch contacts are made of fine silver, with gold-plated fine silver contacts available for low-current circuits. The ambient temperature range is -60 °C to +90 °C for the limit switch and -60 °C to +100 °C depending on type and materials, and the switch carries the certification numbers EPS 14 ATEX 1 765 U and IECEx EPS 14.0091 U.

Key Features

• Electrical equipment in Zone 1 / Zone 2 gas atmospheres
• Mining installations where the Ex db I Mb certification applies

Specifications

Compatibility & Integration

The insert switch is mounted into the flameproof enclosure of the equipment it controls, with the wiring made inside the enclosure in accordance with the installation rules for Ex d equipment. Installation and maintenance must be carried out by trained personnel authorised for work in explosive atmospheres, and the switch must never be mounted or removed while energised, per the BARTEC operating instructions.

Before ordering, confirm the switch configuration and the electrical rating of the circuit it will control, so the correct 07-1511 variant can be matched to the application. Our team can verify the part number against your requirements before dispatch.

Housing and Mechanical Durability

The 07-1511 insert switch is built with thermoplastic housing components and a stainless steel switching plunger, and is rated to IP 66 per IEC 60529 for protection against dust ingress and powerful water jets — a relevant rating for outdoor Ex d equipment exposed to GCC dust storms and washdown cleaning. BARTEC rates the mechanical life of the switch contacts at more than 2 x 10&sup6; switching cycles, and offers both silver and gold-coated contact variants so the correct contact material can be matched to the current and voltage of the controlled circuit.

Because the switch is fitted inside a certified Ex d enclosure, replacement must preserve the flameproof joint and certification of the parent equipment; Seven Star LLC verifies the exact 07-1511 variant, contact material, and core length against the customer’s equipment before supply.
