	NOTE: See Cradle Catalog Numbers for cradle catalog numbers.

P-Frame Drawout Mechanism

The drawout assembly mechanism allows the circuit breaker to be racked in four positions (connected, test, disconnected, or withdrawn), as shown in the figure below.

Connected Position	Test Position	Disconnected Position	Withdrawn Position

NOTE: For UL/CSA Listed devices, the clusters are mounted on the circuit breaker and the stabs are on the cradle. For IEC devices, the clusters are mounted on the cradle and the stabs are mounted on the circuit breaker.

P-Frame Cradle Accessories

P-Frame Cradle Position Switches

Three optional cradle position switches are available for the cradle:

Cradle position switches (CE) to indicate the connected position
Cradle position switches (CD) to indicate the disconnected position. This position is indicated when the required clearance for isolation of the power and auxiliary circuits is reached.
Cradle position switches (CT) to indicate the test position. In this position, the power circuits are disconnected and the auxiliary circuits are connected.

P-Frame Cradle Locking and Interlocking

Disconnected Position Locking

The circuit breaker can be locked in the disconnected position by key interlock (optional, catalog number S33772) or padlock (standard). The key interlock is on the cradle and accessible with the door locked.

Kirk key interlocks are available for UL/CSA circuit breakers. Key is captive when circuit breaker is closed.
Locking in all positions (disconnected, test, and connected) is possible. Factory standard setting is locking in disconnected position.

Door Interlock

The door interlock (catalog number S33786) prevents the compartment door from being opened when the circuit breaker is in the connected or test position. If the circuit breaker is put into the connected position with the door open, the door can be closed without disconnecting the circuit breaker. For greater protection, this interlock can be used in conjunction with the open door racking interlock.

P-Frame Open Door Racking Interlock

The racking interlock (catalog number S33788) prevents racking in the circuit breaker when the door is open. (Insertion of the circuit breaker racking crank is not possible when the compartment door is open.)

Cradle Rejection Kits

The cradle rejection feature (optional, catalog number S33767) ensures that only the properly designated circuit breaker or switch is matched with the selected cradle assembly.

P-Frame Cradle Miscellaneous Accessories

Shutter and Shutter Lock

The shutters automatically block access to the main disconnects when the circuit breaker is in the disconnected, test, or fully withdrawn position. The shutter lock is used to prevent connection of the circuit breaker or to lock the shutters in the closed position.

The optional shutter assembly (catalog number S48933) consists of shutter and padlock provision.

Door Escutcheon (CDP)

The door escutcheon (catalog number S33857) provides a frame and seal for the circuit breaker.

Transparent Cover for Door Escutcheon (CCP) (P-Frame Only)

The door escutcheon cover (catalog number S33859) is hinge-mounted and is designed to be installed on the door escutcheon for the P-frame drawout circuit breaker.

		NOTE: All diagrams show circuit breaker in tripped position.
A–Do not remove factory-installed jumpers between Z3, Z4 and Z5 unless ZSI is connected. B–Do not remove factory-installed jumper between T1 and T2 unless neutral CT is connected. Do not install jumper between T3 and T4. C–For proper wiring of neutral CT, refer to Instruction Bulletin 48041-082-03 shipped with it. D–24 Vdc power supply for trip unit must be separate and isolated from 24 Vdc power supply for communication modules. E–For proper wiring of the FDM, refer to user guide 5100512864A-02.

Connections

PowerPacT and ComPacT circuit breakers are connected to the ULP devices (FDM121 display, IFM, IFE or IO module) via the circuit breaker ULP cord.

Cord is available in three lengths: 0.98 ft. (0.35 m), 4.3 ft. (1.3 m) and 9.8 ft. (3 m).
Lengths up to 32.9 ft. (10 m) are possible using extensions.
