Rauscher & Stoecklin High-Current Connectors

Rauscher and Stoecklin Connector

The robust construction, corrosion-resistant design and resilient silver plated contacts of the Rauscher & Stoecklin high current connectors are key factors in their selection for use in harsh environments.

The Rauscher & Stoecklin pin and sleeve style contacts also rectify arcing and pitting issues common with butt style contacts. The 250A and 400A versions feature contacts that are exchangeable from the front side without removing the connected cable.

These plugs and sockets are designed for loads from 200 to 400 Amps and 1000 VAC. See below for a breakdown of specifications and applications.

When ordering a connector it is not always as simple matter of determining between 'male' and 'female' because this can refer to both the housing gender and the contact gender. Many manufacturers offer a given housing gender with both pin and socket. A common example of such confusion occurs in the Deutsch Industrial DT range, where the plug (or male connector) actually contains socket (or female) contacts. For this reason please specify both the contact and housing gender at the time of order.

The IP Rating of a connector or accessory relates to the degree of ingress protection provided by that component. The first digit of the code relates to the degree of protection against access to hazardous parts (conductors etc) and against solid foreign objects. The second digit refers to the degree of protection against the ingress of water. For two examples of this system, consider the most commonly seen IP ratings in our products: IP44 and IP67. IP44 4: Protection from solid objects ≤1mm | 4: Protection against splashing water IP67 6: Protection from dust-sized objects | 7: Protection against immersion in water at depth of 1m for 30mins A complete guide to all IP Ratings is available here.

These terms are used by Phase 3 and ITT Veam on their high-current connectors.The source is considered the half of the connection from which the power is sourced; or the half supplying the electrical power. In an emergency power application, the generator is the source and would be fitted with Panel Source (panel-mount) connectors, a Panel Source Powersafe Box, or Line Source (inline) connectors on pigtails. The drain is the half of the connection which drains the power from the source. In the same emergency power application described above, the network receiving the emergency power supply is the drain and would be fitted with Line Drain connectors, Panel Drain connectors or a Panel Drain Powersafe Box.

We commonly deal with both American Wire Gauge (AWG) and square millimetre (mm2) dimensions as the units used by manufacturers can vary. To convert between measurements please refer this conversion chart.
