The M-7679 R-PAC offers protection, automation, and control capabilities

for recloser, switch, sectionalizer, and advanced distribution automation

applications. It has over 30 protection elements for optimal protection

of power distribution systems. It is compatible with three-phase ganged

and independent phase capable switching devices such as reclosers,

switches, sectionalizers, and breakers. It has up to six standard or low

energy analog (LEA) voltage inputs. The M-7679 R-PAC has a recloser

settings wizard that assists in creating files for most common settings

for recloser applications. The comprehensive I/O matrix provides visual

The M-3908 Universal Contact Input Adapter will convert seven internally

wetted status inputs of Beckwith relays to be externally wetted.

The input voltage is selectable: 250 V dc, 125 V dc, 48 V dc, 24 V dc or

12 V dc. This selection is made through a series of jumpers (Table 1) on

the printed circuit board. Each of the externally wetted inputs will be

isolated from all other externally wetted inputs. Input to Output is optically

isolated.

The B-6200A-U1 Hinge Kit contains all necessary components for field

installation of two hinges and a latch onto the M-6200A Control for

retrofitting into the M-2900A Cabinet.

Features

Some installations of the M-2001 series Tapchanger Control may

experience interposing relay buzzing, chatter (severe buzzing), or in

extreme cases, lock-up and runaway tap changer operation.

With sensitive coil configurations, even though the pull-in current is

usually in excess of 10 mA, the “maintain” or “holding” current can

be as low as 1-2 mA. At that level, the leakage current from

protective components in the M-2001 series control, can cause the

relay armature to buzz or lock-up the interposing relay.

Adding shunt resistance to each of the output relay circuits will

minimize the interposing relay’s sensitivity to small leakage currents,

thereby eliminating the relay buzz, chatter, and lock-up.

For this reason, the B-2048 Resistor Assembly is provided with this

Adapter Panel or Terminal Block assembly. When

required, install the B-2048 on the Terminal Block as shown in the

Table below.

Battery Charging Features

The M‑2032B is designed to charge a 24 V sealed lead‑acid battery. It includes an

internal circuit to prevent overcharging of the batteries and extend their life.

• Tri‑Level Bulk/Absorption/Float Charger with Pre‑Charge

• When battery voltage is below 21 Vdc the charge current is limited to 40 mAdc

(Pre‑Charge), once the battery voltage is greater than 21 Vdc, the charger will begin

charging at the higher rates (Bulk/ Absorption/Float).

This prevents high current in a damaged battery. The Bulk mode charges the battery

at a rate that minimizes charge time and maximizes battery capacity. The Float mode

maintains the battery charge after the Bulk mode charge has finished, preventing

overcharging of the battery.

• The battery charge voltage is temperature compensated to optimize battery

charge and life.
