Phase 3 Powersafe Sequential Mating Box
The Phase 3 PowerSafe sequential mating box is fast becoming the industry standard in generator and high-current connections. The unit is available in Source or Drain versions rated at 800 Amps to be compatible with all Phase 3 500 and 800 Amp connectors as well as Veam 400 and 660 Amp connectors. The sequence of connection and disconnection is controlled to ensure safety circuits are connected first and disconnected last.

The PowerSafe box can be panel-mounted, providing the most cost-effective solution, or brought out to an external or safe position. Large power connections can be catered for by stacking the units allowing for even the largest of low-voltage supplies to be connected in a safe way.
Advantages of PowerSafe Box
Safe Connections The three phases, neutral and earth connections cannot be made in the wrong order due to the sequential mating mechanism at the heart of the PowerSafe Box.
Individual connectors are mounted in a single IP67 (when mated) enclosure. There is no need to fabricate holes for five individual connectors and their associated fasteners.
Some electrical regulations required hardware to be made of non-conducting materials. The PowerSafe Box is insulated, giving greater freedom in fastener specification.
A special locking key is required to plug or unplug all connectors so only authorised persons in possession of the key can connect and disconnect the PowerSafe Box.
A remote control function can be configured via the rear-mounted connector to disconnect the power should someone try to unlock the box.
Rugged & Waterproof
Flip-up protective covers are built in and form part of the mating dequence giving IP65 protection to the unmated box. When the connectors are installed the box is rated IP67.
The Phase 3 PowerSafe Box complies with AS/NZS 3000:2007 wiring standards.

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.
