Industrial Power Connectors

Three-phase connectors for 500 and 800 Amp temporary power and generator applications.


Phase 3 Powersafe Connectors

Connectors and Sequential Mating Boxes from Phase 3 are the industry standard for making connections to single phase and three phase generators plus numerous other equipment requiring connectors with current ratings up to 800 Amps each.

Phase 3 Powersafe Connectors

Phase 3 Powersafe single pole connectors are amongst the highest rated and safest connectors of their type on the market. They have been tried and tested in some of the harshest environments worldwide for guaranteed reliability. Standard safety features include a secondary locking system which requires a key to unlock the connection. This is in addition to fingerproofed electrical contacts on all Phase 3 connectors, which reduces the risk of accidental contact when the connector is live.

Connector-Tech ALS can supply both Phase 3 and Veam, however, we consider the Phase 3 version to be of superior quality as well as being more cost effective. Phase 3 connectors have been created by the same principal designer of the Veam Powerlock series who made a significant number of design improvements including higher current, temperature and IP ratings. The Phase 3 versions have been tested by an independent laboratory (ERA UK). Full ERA test reports are available upon request.

Advantages of Phase 3 Connectors

  • Increased current-carrying capacity (up to 25%): 500/800 Amp (PowerSafe) compared with 400/660 Amp (Veam)
  • Increased surge-current rating
  • Increased short-circuit rating
  • Increased ingress protection rating
  • Reduced insertion force
  • Improved cable strain relief
  • Improved impact resistance
  • High-temperature resistant materials
  • Panel-mount connector mounting plates
  • Rubber hand grips as standard for ease of coupling and added impact protection
  • Rubber protective caps to protect connectors from moisture, dirt and abrasion when uncoupled (optional)
  • RoHS compliant

100% Compatible with ITT Veam PowerLock Connectors
Compatibility is guaranteed by Phase 3 between their Powersafe products and Veam Powerlock connectors. PowerSafe was designed by principal members of the original Veam engineering design team, who had developed this format of connector, and have been integrally linked with the subsequent development of these types of products over the last decade. The PowerSafe design is guaranteed to be 100% intermateable with Veam Powerlock style connectors, while the redesign of the active contact element and material compositions has up-rated the current-carrying capacity and the short-circuit ratings of the connector.

Made in the UK
Phase 3 products are manufactured to the highest-possible standards and the quality of both the individual connectors and the PowerSafe Box exceeds that of similar items from all other manufacturers.

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.
